Additionally, effective as of the Combination Date, unvested and unexercised stock-settled equity-based awards (which included 2.1 million of CB&I restricted stock units and stock options to purchase 0.1 million shares of CB&I’s common stock) were canceled and converted into comparable McDermott stock-settled awards with generally the same terms and conditions as those prior to the Combination Date.

NO105―In December 2010, J. Ray McDermott (Norway), AS ( “JRM”), one of our indirectly wholly owned subsidiaries, and Oceanteam ASA entered into an Equity Owner’s Agreement (as amended to date, the “Equity Agreement”), under which JRM acquired 75% interest in NO 105 AS, the vessel-owning company. Under the Equity Agreement, JRM was given an option to purchase Oceanteam ASA’s 25% ownership interest in the second quarter of 2017.

In the second quarter of 2017, JRM exercised its option under the Equity Agreement and purchased Oceanteam’s 25% interest in the vessel-owning company for approximately $11 million in cash. As part of that transaction, JRM also assumed the right to a $5 million note payable from NO 105 AS to Oceanteam (which had been issued in connection with a dividend declared by NO 105 AS in 2016). In connection with this acquisition, we recorded a $9 million decrease in Noncontrolling interest and a $5 million decrease in note payable to Oceanteam, and we recognized a $2 million gain in Capital-in-excess of par value in our Consolidated Financial Statements.

Berlian McDermott Sdn. Bhd―In 2013, we entered into certain joint ventures with TH Heavy Engineering Berhad (“THHE”), whereby we acquired a 30% interest in THHE Fabricators Sdn. Bhd. (“THF”), a subsidiary of THHE, and THHE acquired a 30% interest in our Malaysian subsidiary, Berlian McDermott Sdn. Bhd (“BMD”). In the third quarter of 2016, we reacquired the 30% noncontrolling interest in BMD from THHE in exchange for our 30% equity interest in THF. We determined the fair value of the asset surrendered to be $17 million. In connection with the acquisition of the BMD noncontrolling interest, we recorded an $18 million decrease in Noncontrolling interest, and, in connection with the exchange of our investment in THF, we recorded a $12 million decrease in Investments in unconsolidated affiliates and a $5 million gain in Other income (expense), net, in our Consolidated Financial Statements.
